The 1950 United States Senate elections occurred in the middle of Harry S. Truman's second term as President. As with most 20th-century second-term mid-terms, the party out of the Presidency made significant gains. The Republican opposition made a net gain of five seats, taking advantage of the Democratic administration's declining popularity during the Cold War and the aftermath of the Recession of 1949. The Democrats held a narrow 49 to 47 seat majority after the election. This became the first time since 1932 that the Senate Majority Leader lost his seat and the only instance where the majority leader lost his seat while his party retained the majority.
The 1948 United States Senate elections were elections which coincided with the election of Democratic President Harry S. Truman for a full term. Truman had campaigned against an "obstructionist" Congress that had blocked many of his initiatives, and in addition the U.S. economy recovered from the postwar recession of 1946–47 by election day. Thus Truman was rewarded with a Democratic gain of nine seats in the Senate, enough to give them control of the chamber.
The United States Senate elections of 1944 coincided with the re-election of Franklin D. Roosevelt to his fourth term as President. The Democrats' large majority remained the same, but they lost one seat to the Republicans in a special election.
